System.error NullPointer

System.error NullPointer - android

I try to write to share a post on twitter but this code works on Galaxy S2 but it doesn't work in Galaxy s3...I don't know why.
At this link there is the log error:

I try this code in other real device. In one device works great but in my device the same code doesn't work. Anyone can help me to understand why?

It looks like twitter is null here
AccessToken at = twitter.getOAuthAccessToken(
requestToken,verifier);
because this method is called before you run your AsyncTask which initializes your twitter variable.
Try calling this method in onPostExecute() of your AsyncTask since this method will be called when doInBackground() is finished.

Repeat Alarm manager in Sending SMS not Sending

I created application that if the button is click it will send SMS to the number that came from webservice. Then I use Alarm Manager to send SMS repeatedly in the number that i get from the web service. It is working fine but when I change the number that I want to send an SMS it will not work. I don't know what is wrong with my code. Here is my code.
This is my code that send an SMS.

}
This is my manifest to allow sending SMS and to register the alarm receiver.

Application with Internet for the main and without for the rest

I have an app in which starting page needs internet,
Rest want to work without internet (ie, only one activity need the internet permission).
But when I turn off the Internet, the app shows a message like turn internet connection on and then only I can proceed to further (Here i want to work with out internet).
Is there any solution for that?

It seems you didn't write this Android application by yourself (or else you would understand what the message means). This message that "asks for internet connection" is something that is done through your app and not by the Android framework. Please understand your application first, then ask questions about it.
Hint: Search for the String inside your app (by search functionality of your IDE) that is shown in your "asks for internet connection" message and look up why it is displayed. You will see, that you can disable it.

in your AndroidManifest.xml put :
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />
and inonCreate method of each activity you don't want to use the internet_connection in:
WifiManager wifiManager = (WifiManager)this.getApplicationContext().getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(false);

You can only set permission for the complete app, not on single activity.
Why is it so important that the user doesn't have an internet connection in the rest of the app? When you don't code anything that connects to the internet in those "internet-free" activities, then you won't use up the (possible) date

Why am I getting this error "android.view.InflateException: Binary XML file line #29: Error inflating class fragment"

I am using Google Map v2 in Tabs.

I capitalize fragment but I got this warning "Invalid tag Fragment should be fragment"

Why onPushMessageReceived() is not called in Geoloqi API in Android?

In my android app i am using Latest Geoloqi API to implement Geofence concept.when user entered into some region he has notify, for that purpose i am using Push Notifications.in GeoReceiver class three callback methods are calling but not onPushMessageReceived().please help me how to do it?
I am creating trigger with current location is it required to enter into region manually or since i am already in the location its not calling?
